What information is contained in Box 9 of the CMS-1500 form?

Box 9 of the CMS-1500 form is specifically designed to capture information related to a patient’s other insurance coverage. This is crucial because it helps indicate whether the patient has additional health insurance that may be responsible for the payment of the services provided. By detailing other insurance coverage, this box facilitates proper coordination of benefits between multiple insurers, ensuring that claims are processed correctly and that the patient is not held liable for costs that should be covered by another policy. This box's function underscores the importance of comprehensive coverage in healthcare billing and helps prevent payment discrepancies that can arise when multiple payers are involved.

The other options pertain to different aspects of patient information not associated with Box 9. For instance, the patient's primary care physician may be recorded elsewhere in the form, prescribed medication details are typically not included in the CMS-1500, and treatment facility information is noted in other specific sections as well.
